' itself, thus making it unnecessary for the brakeman to go -between the cars' an'drisk being maimed or killed. r A further object-of thisinvention is`to' provide a train or air pipecoupling in which :provision is made to take u the usual yer-.- tical or rectilinear motionl etwee'n the a d-, jacentcars` and which allows the required' l'lateral play between the"` two respective sec- Y tions of. the couplerwhen the cars are round- -`ingacurve. A 1 .2.5 lViththe foregoing` and other objectsin `view this invention consists in the novel fea ,turesof`con'struction, combination and arrangement' of parts illustrated 'in the drawin and 'more particularlypointed out in .'30 the appended claims.

Fig. 2 is 3.5 'an elevation of lthe two sectionsof thecou'- p ler as arranged in juxtaposition. y Fig. 3 is 1a similar view, with the coupler sections in coupled .-relation. Fig. 4 is a plan view of the sections -shownin Fig.- 2.. Fig. 5 is a "40. plan view of-a section of oneofthe couplerl members, with parts shownin section. Fig.

i 6`of ,-tiiei'car and a supportingarm 7 which extends outwardly from the attaching frame.l

.in an approximately 'horizontal plane. -The outer ends of the supporting arms 7 carry theoppositely disposed laterallyspaced supporting yokesf8- which support the interlocking members 9y of the coupler. The

' members 9 consist,A each, of a supporting 4arm 10 provided at itsouter endjand at vopposite:edges with the vertically disposed guldexplates 1 1 -fornied upon their outer aces with the bearin flanges 12 which fit. and work againstthe inner edges of the side pieces 13 of lthe yokes '8.- From the foregoing-lit will be readily seenthat the yokesl 8 arecapable of'j'a vertical slidingl action or' .movement with respectfto the interlocking l'members-Q whichl'allows for the usual vertical or rectilinear movement between the 'vad- Jacent'cars. -Each of the interlocking members 9 furthercomprises a-pair of vertically spaced uidebarsI/twhich receive the-arms 10. of t e opposite member of the coupler when said members come together.- The outer. ends of the -bars 14 are beveled out-- 'wardly, as at 15,' and the corresponding ends of the'bars 10 beveled upon opposite faces, vas at16,`to insure the engagementof these parts when the coupler members come together..l Each of the coupler members furthercomprises theswinging arm 17 pivoted Aat vits upper end, asl at 18, b meansl of a shaft 26. The lower ends of tlie arms above mentioned are provided with the interlocking heads 19, comprising the circular bear`l ing portions 2,0"- -1n which are arranged the rubber gaskets or washers 21, the pur. pose of which is to prevent any air leak- Y age lwhen the coupler members are in coupled relation. Each of theinterlocking'heads 19 is provided with the oii'set locking ear 22 at :one point and with the ear receiving flange 23 at an opposite point. The flanges 23f-are provided ini their vinner faces witharcuate recesses 24 whlch receive corres'ponding ribs '25 formed upon the inner faces ofthe locking ears122; Whe-n the two members of thev cou ler areapart, as shown in Figs. 2. and4, tie" arms 17 are held in a depending positiyqn by the fiat springs 26. ``When the rs come. together, however, the pivotal connections 18' pass eachother the .heads-1,9 interlock and `cause the arms to swin npinto the4 position indicated in Fig. 'ier which conditions the bearing heads A and gaskets 4 21.ft tightlyagainst eachother l j mounted to'turn 27 and 28 arearranged on the outer faces of and connect the air or train pipe between the cars.

The upper ends of the arms. 17 are connected with shafts 26 which extend through the gulde platesA` 11 and the outer ends of.l

the supporting arms 10,'.as shown, and are 1n their-bearings. Cams the guide plates 11. The cams 27 work against the inner faces of the upper endsof the swinging arms,

lagainst the arms 28carried bythe axles 26.

17 and the cams 28 The purpose of the cams 27 is to force the 'fears 22 and heads 2.3 into effective locking i enga ement when the cars come together.'

@s t e armsswing from the verticalposition to that ndicated'n F i 3, the arms `17 ride up on the cams 27, t ereby forcing the heads 19 laterally towardeach Iother.

The purpose1of the cams 28 and arms 28 is.A

to shift f the heads 19 laterally in=opposite directions to separate the heads. When the .couplings are separated, thearms 28 will swing from thefposition shown in Fig. 3 to the vertical positfon. In so doing, they will ride up onthe cams 28 to shiftthe heads laterally'- as described. It is to be noted-that u cams 28. shift the heads in a direction opposite tothat of cams 27.

. -From the foregoing-description taken in ."cdnnection with the drawings, it is thought tht the construction and operation of;this

, inention will ciples .orsacricing any o be readily understood without requiring a more extended explanation. l' Various changes in the form, proportions and minor details of constructionmay beresorted to without departing from the printhe advantages of this vinvention as defined in the appended claims. Having described this invention, what is 'claimed as new, is:-

1. A coupler of the class described comprislng a pair of supporting members adapt-l ed f or attachment to adjacent cars, .depending supporting yokes carried by said members, lnterlocking'members to hold the two sections of the coupler in coupled relation when the cars come together, swinging arms carried by the'interlockinmembers, and in;

terlocking heads carried y the lower ends o f the arms adapted to interlock as thearms pass feach other to -thereby couple the two sections of the train or air pipe coupler together when the cars come to ether.I

2. A`coupler of the class escribed com- .prising a pair of supporting members ada ted fpr attachment to adjacent. cars,guid1ng members adapted to interlock when the cars come together and hold the two sections of the coupler in coupled relation, yokes depending from the supporting memsupporting bers and havinga sliding engagement with the guiding members, swinging oted to. the guiding members, heads'at the lower ends ofthe of interlocking engagement arms p'ivmterlocking arms, means between the heads, cams to force and hold said heads in ,effective locking engagement when the cars cometogether, and other cams to .break the engagement. between said heads when the cars move apart whereby the two sections of thecoupler will'automatically uncouple.

3. 4A coupler of the vclass-described comprising 'a pair of supporting members adapted. for attachment to adjacent cars, guiding members adapted to interlock when the cars come together and hold the two sections of the coupler in coupled relat1on, supporting yokes depending' from the supportlng mem,-
